示例1: RewriteTupleConversion

        private BoundExpression RewriteTupleConversion(
            CSharpSyntaxNode syntax,
            BoundExpression rewrittenOperand,
            ConversionKind conversionKind,
            bool @checked,
            bool explicitCastInCode,
            NamedTypeSymbol rewrittenType)
        {
            var destElementTypes = rewrittenType.GetElementTypesOfTupleOrCompatible();
            var numElements = destElementTypes.Length;

            ImmutableArray<FieldSymbol> srcElementFields;
            TypeSymbol srcType = rewrittenOperand.Type;

            if (srcType.IsTupleType)
            {
                srcElementFields = ((TupleTypeSymbol)srcType).TupleElementFields;
            }
            else
            {
                // The following codepath should be very uncommon (if reachable at all)
                // we should generally not see tuple compatible types in bound trees and 
                // see actual tuple types instead.
                Debug.Assert(srcType.IsTupleCompatible());

                // PERF: if allocations here become nuisance, consider caching the TupleTypeSymbol
                //       in the type symbols that can actually be tuple compatible
                srcElementFields = TupleTypeSymbol.Create((NamedTypeSymbol)srcType).TupleElementFields;
            }

            var fieldAccessorsBuilder = ArrayBuilder<BoundExpression>.GetInstance(numElements);

            BoundAssignmentOperator assignmentToTemp;
            var savedTuple = _factory.StoreToTemp(rewrittenOperand, out assignmentToTemp);

            for (int i = 0; i < numElements; i++)
            {
                var field = srcElementFields[i];

                DiagnosticInfo useSiteInfo = field.GetUseSiteDiagnostic();
                if ((object)useSiteInfo != null && useSiteInfo.Severity == DiagnosticSeverity.Error)
                {
                    Symbol.ReportUseSiteDiagnostic(useSiteInfo, _diagnostics, syntax.Location);
                }
                var fieldAccess = MakeTupleFieldAccess(syntax, field, savedTuple, null, LookupResultKind.Empty);
                var convertedFieldAccess = MakeConversion(fieldAccess, destElementTypes[i], @checked);
                fieldAccessorsBuilder.Add(convertedFieldAccess);
            }

            var result = MakeTupleCreationExpression(syntax, rewrittenType, fieldAccessorsBuilder.ToImmutableAndFree());
            return _factory.Sequence(savedTuple.LocalSymbol, assignmentToTemp, result);
        }
